Anti-clay sacrifice agent for inhibiting interlayer adsorption performance of clay minerals and preparation method of anti-clay sacrifice agent
The invention discloses an anti-clay sacrifice agent for inhibiting the interlayer adsorption performance of clay minerals and a preparation method of the anti-clay sacrifice agent, and aims to solve the technical problem that most of filtrate reducers in the prior art are poor in temperature resistance and salt resistance. The preparation comprises the following raw materials in parts by weight: 60-100 parts of unsaturated polyether monomer; 20 to 24 parts of unsaturated quaternary ammonium salt monomer; 3-7 parts of a main chain rigidity and flexibility modifier; 1 part of an oxidant; 1 part of a chain transfer agent; 1 part of a reducing agent; and 370 to 410 parts of deionized water. The anti-mud sacrifice agent provided by the invention has relatively strong capability of inhibiting the adsorption performance of clay minerals, and the synthesis cost of the anti-mud sacrifice agent is greatly reduced compared with that of the prior art, so that the anti-mud sacrifice agent can be widely popularized and applied in the fields of concrete manufacturing and machine-made sand manufacturing.
本发明公开了一种用于抑制黏土矿物层间吸附性能的抗泥牺牲剂及其制备方法，以解决现有技术中的降滤失剂大多抗温性能差抗盐能力也差的技术问题。其制备包括下述重量份的原料：不饱和聚醚单体：60～100份；不饱和季铵盐单体：20～24份；主链刚柔性改性剂：3～7份；氧化剂：1份；链转移剂：1份；还原剂：1份；去离子水：370～410份。本发明提供的抗泥牺牲剂有着较强的抑制黏土矿物吸附性能的能力，且其合成成本较现有技术有大幅降低，更加有利于抗泥牺牲剂在混凝土制造领域和机制砂制造领域的广泛推广应用。
